ET8 PLC equipment
ET8 PLC equipment enables reliable single- double- or triple-channel analog PLC links on high-voltage lines in frequency ranges from 20 kHz to 1000 kHz (1 MHz).
Main features
- Fully AF and RF on site programmable without changing any hardware
- Structural flexibility - easy integration of AF options (NF8, DZ8, TG8, etc.)
- Modularity - easy on site modifications (expansion or reduction) of the device structure (changes to the number of channels and of the output power)
- Accessibility of information - status of PLC equipment (alarms, operational parameters, etc.) may be accessed from local and remote PLC terminal
- Programmability by means of either a personal computer (PC) or integrated MMI console
Technical data
| Extended carrier frequency range (RF range) | 20kHz to 1000kHz |
| Number of duplex PLC channels | 1, 2 or 3 (up to 6 on request) |
| PEP (Peak Envelope Power) | 10, 20, 40 or 80W |
| Nominal channel bandwidth | 4kHz |
| Useful AF bandwidth | 300Hz to 3720Hz |
| Permissible line attenuation | <52dB (10W/channel) |
| Synchronization | yes - total ("master-slave" principle) |
Applications
- Reconstruction, expansion and/or upgrading of the existing telecommunication system
- Establishing of back-up channels
- Transmission of teleprotection signals
